TNETV107X is a Texas Instruments SoC based on an ARM1176 core, and with a bunch on on-chip integrated peripherals. This patch adds support for the TNETV107X EVM board.
Signed-off-by: Cyril Chemparathy cyril@ti.com --- v6: moved async emif config, and pll config to board code v6: moved pll and aemif initialization to board init v6: enabled NAND BBT and JFFS2 support v5: rebased on master in u-boot-arm.git (unchanged) v4: rebased on next in u-boot-arm.git (unchanged) v3: Added NAND MTDID comment in board config v2: Added maintainers entry v2: Fixed sort order in main makefile v2: Remove board specific linker script v2: Style fixes - multiline comments v2: Replaced clk_get() with clk_get_rate()
